Or $750/lb. SpaceX pricing for the Falcon 9 and Falcon 9 heavy:

For comparison, the Delta IV Heavy costs $375,000,000 with a LEO payload of 28,790 kg/63,470 lbs, or $13,025/kg or $5920/lb.
SpaceX stands a decent chance of monopolizing the launch market in the US. And while the price does not include a Dragon capsule, the US is currently paying the Russians $70 per astronaut to fly on a Soyuz. That’s more than the price of an entire Falcon 9 launch which, with a Dragon V2 capsule, should carry 7 astronauts.
